Some advanced Sabermetrics questions

0 votes
I'm writing sort of an uber line up analysis and need some help with the stats.

I read about ultimate base running (UBR or BSR) as a way of summing up a batter's baserunning ability excluding base stealing. Does anyone have a chart / estimation regarding a batter's chance to go 1st to 3rd or 2nd to home on a single based on his BSR?

Secondly, I'm wondering how GB% effects double plays for a batter. Does a batter's GB% raise, drop or remain even with a runner at first? Also if anyone here knows about the chances of a double play based on GB% (assuming a runner at first).

Also if there's a site for all those sort of charts (I don't mind paying if the fee is reasnoble) it would be much obliged.

I ran a query based off your second question, and these were the results:

BASE_STATE GB% FB% LD% PU%*
Bases Empty 44.9 36.9 18.1 7.8
1-- 43.7 37.5 18.8 7.8
-2- 46.3 35.8 17.8 7.7
12- 44.7 37.2 18 8
--3 45.3 36.9 17.8 8
1-3 44.9 37.2 17.9 7.9
-23 46.1 36.6 17.3 7.9
123 44.2 37.9 17.9 8.5

Thanks a lot, +1. And by the way, where did you run this query?

I ran it using a SQL program and the retrosheet files.

Your 1st question is definitely answerable, but it would take a bit of data-collecting. In their Base Running and Misc table, B-ref has an Extra Base Taken % or something similar if you are interested in that, as well as 1st-to-3rd and 2nd-to-home data.

I wrote something for BTB about your question, it may interest you.

Read the article, some interesting points. I think the steady GB% is a result of the batter's effort to lift the ball up balancing the heavier array of sinkers / 2smers down in the zone. While I don't have the stats to back the talk I'm pretty sure that in DP situations the amount of "Ground ball pitches" rise significantly, so I assume the batter's effort not to hit into the dp is what balances the scale.
